A novel actinomycete strain PS42-9(T), which formed short chains of spores borne on the tip of long sporophores arising from the substrate mycelium, was isolated from soil in Phu-Sang National Park, Phayao province, Thailand. The isolate contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The whole-cell sugars of strain PS42-9(T) were glucose, madurose, mannose, rhamnose and ribose. The characteristic phospholipids were phosphatidylethanolamine, phosphatidylmethylethanolamine, hydroxyphosphatidylethanolamine and ninhydrin-positive glycophospholipids...

A polyphasic taxonomic study was performed on a novel strain designated as 04OKA-3-121(T), which was isolated from the hard coral Galaxea fascicularis L. collected at Akajima, Okinawa, Japan. These bacterial cells were observed to be pale-yellow, Gram-stain-negative, strictly aerobic, chemoheterotrophic, non-spore forming, non-motile, and rod-shaped. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel marine isolate is affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and that it shared the highest (93...

Transition state theory proposes that stable chemical mimics of enzymatic transition states will be powerful inhibitors of their cognate enzymes. The Immucillins are chemically stable analogues that mimic the ribocation and leaving-group features of N-ribosyltransferase transition states. Infectious disease agents often rely on ribosyltransferase chemistry in pathways involving precursor synthesis for nucleic acids, salvage of nucleic acid precursors from the host or synthetic pathways with nucleoside intermediates...

For the first time, the cis/trans isomer content of menaquinone-7 in food products has been identified and marked. A novel method of marking isomers of vitamin K2MK-7 in dietary supplements was developed and validated. Five different isomers of cis/trans vitamin K2MK-7 were identified. Identification of cis/trans isomers was performed by HRMS-QTOF, whereas their quantities were determined by using CAD and DAD detectors. In the majority of cases, the content of biologically active all trans vitamin K2MK-7 was below its declared content...

Two novel strains, J116-2(T) and J116-1, were isolated from forest soil and were taxonomically characterized by a polyphasic approach. Both strains were yellow-coloured, Gram-stain-negative, strictly aerobic, non-motile and rod-shaped bacteria. The strains were non-sporulating, catalase-positive and oxidase-negative. Strains J116-2(T) and J116-1 were able to grow at 20-32 °C, pH 6.0-8.5, and 0-0.5 % (w/v) NaCl concentration. Based on 16S rRNA gene sequence analyses, strains J116-2(T) and J116-1 formed a distinct lineage within the family Chitinophagaceae of the phylum Bacteroidetes and were closely related to genera Taibaiella (89...

Menaquinone-7 (MK-7) is the key form of vitamin K used as a dietary supplement and its production revolves around Bacillus subtilis natto. Current fermentation strategies, which suggest static fermentations without aeration and agitation, can be problematic for large scale MK-7 production due to biofilm formation. The use of biofilm reactors, therefore, is proposed in the present study, which could utilize both agitation and aeration without interrupting MK-7 secretion. In this study, biofilm reactors were constructed using the selected plastic composite support (PCS) and B...
